Graph Algebras and Derived Graph Operations

open access: yesLogics, 2023
We revise the definition of graph operations in [WDK2018] and adapt correspondingly the construction of graph term algebras. As a first contribution to a prospective research field Universal Graph Algebra, we generalize some basic concepts and results from algebras to graph algebras.

Binary operation graphs [PDF]

open access: yesAIP Conference Proceedings, 2019
A graph labeling is an assignment of integers to the vertices, edges, or to both, and it is subject to certain conditions. In this paper, a new concept of graph labeling called binary operation labeling is introduced. Let G=(V, E) be a (n, m)-graph and let f: V(G) → 1, 2, …, n be a bijection.

Vertex-Based Topological Indices of Double and Strong Double Graph of Dutch Windmill Graph

open access: yesJournal of Chemistry, 2021
A measurement of the molecular topology of graphs is known as a topological index, and several physical and chemical properties such as heat formation, boiling point, vaporization, enthalpy, and entropy are used to characterize them.

Designing classes’ interfaces for neural network graph model

open access: yesТруды Института системного программирования РАН, 2019
An approach to testing artificial neural networks is described. The model of neural network is based on graph theory, and operations that are used in theoretical works devoted to graphs, trees, paths, cycles, and circuits.

OPERATIONS ON SPECTRAL FUZZY GRAPHS

open access: yesJOURNAL OF RAMANUJAN SOCIETY OF MATHEMATICS AND MATHEMATICAL SCIENCES, 2022
The operations in spectral fuzzy graphs such as Cartesian product, strong product, bipartite double, Kronecker product and Lexicographic product (composition) are analysed to elucidate the impact of eigenvalue spectra. Also, the properties are derived which delves the effect on spectral fuzzy graphs.

Quadripartitioned Neutrosophic Graph Structures [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
The quadripartitioned neutrosophic set is the partition of indeterminacy function of the neutrosophic set into contradiction part and ignorance part.

f-Polynomial on Some Graph Operations

open access: yesMathematics, 2019
Given any function f : Z + → R + , let us define the f-index I f ( G ) = ∑ u ∈ V ( G ) f ( d u ) and the f-polynomial P f ( G , x ) = ∑ u ∈ V ( G ) x 1 / f ( d u ) − 1 ,

Feynman motives of banana graphs [PDF]

open access: yes, 2008
We consider the infinite family of Feynman graphs known as the "banana graphs" and compute explicitly the classes of the corresponding graph hypersurfaces in the Grothendieck ring of varieties as well as their Chern-Schwartz-MacPherson classes, using the

Dynamic Graphs on the GPU [PDF]

open access: yes, 2020
We present a fast dynamic graph data structure for the GPU. Our dynamic graph structure uses one hash table per vertex to store adjacency lists and achieves 3.4–14.8x faster insertion rates over the state of the art across a diverse set of large datasets,

Operator Machines on Directed Graphs [PDF]

open access: yesIntegral Equations and Operator Theory, 2010
We show that if an infinite-dimensional Banach space X has a symmetric basis then there exists a bounded, linear operator R : X --> X such that the set A = {x in X : ||R^n(x)|| --> infinity} is non-empty and nowhere dense in X. Moreover, if x in X\A then some subsequence of (R^n(x)) converges weakly to x.
